Conversant in contemporary theory and architectural history, Stan Allen argues that concepts in architecture are not imported from other disciplines, but emerge through the materials and procedures of architectural practice itself. Drawing on his own experience as a working architect, he examines the ways in which the tools available to the architect affect the design and production of buildings.This second edition includes revised essays together with previously unpublished work. Allen's seminal piece on Field Conditions is included in this reworked, revised and redesigned volume. A compelling read for student and practitioner alike.
